SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 328,819, dated October 20, 1885.

Application filed August 6, 1885. Serial No. 173,697.

To all whom it may concern:

Be it known that I, PETER E. SMITH, a citizen of the United States, residing at Scotland Neck, in the county of Halifax and State of North Carolina, have invented certain new and useful Improvements in Spark-Arresters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to certain new and useful improvements in spark-arresters, and the object is to provide a device of this kind, whereby the sparks and cinders will be retained in a suitable receptacle in the smokestack; and the novelty consists in the construction of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

The figure in the drawing is a sectional elevation of my improved spark-arrester.

A A is the smoke-stack, audit is provided with an enlarged chamber B, the mouth a of the stack A terminating in about the center of the enlarged chamber.

0 is an inverted funnel-shaped hood, held (No model.)

in place above the mouth a of the stack by means of braces b, and D is a collar having a conical-shaped flange, 6, corresponding to the incline of the hood. This collar is provided with a set-screw, E, for securing it to the exhaust-pipe E, which may be adjusted above it a suitable distance to secure the best effect in creating a draft in the stack, the direction of said currents being indicated by the arrows.

As the sparks and cinders are drawn up- 40 ward through the stack A they strike the interior incline of the hood and are thrown into the lower portion, G, of the chamber B,where they are below the draft-currents, and consequently remain there until removed through the hand-holes H.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

The combination,with the stack A A, having chamber B and internal inverted funnelshaped hood C, of the exhaust-pipe F, extending through said hood and secured in place by the collar D, as and for the purpose set forth.

In testimony whereof I affix my signature in 5 5 presence of two witnesses.

PETER EVANS SMITH.
